#! /bin/bash

## This shell script (1) remove the white space of all *jpg files in the present folder e.g., 'empirical potential*.jpg', 
## into e.g., 'empiricalpotential*.jpg'. 
## (2) Following that, the script remove the .jpg extension from all the 'empiricalpotential*.jpg'.
## (3) All 'empiricalpotential*' are then converted into 'empiricalpotential*.pdf'
## Essentiall, this script convert all *.jpg file into *.pdf, even if the *jpg files contain white space. 
## After the shell, no more *.jpg remain. 

## Strangely, this scrip will disappear from the current folder after the conversion.

rename "s/ *//g" *.jpg #remove white space in file names

rename 's/\.jpg$//' *.jpg #remove extention .jpg 

#for f in *; do
#     file=$(echo $f | tr ' ' _)
#     [ ! -f $file ] && mv "$f" $file
#done
